Being an entrepreneur means having a dream, a grand vision about what must be changed in the world to make it better. When those dreams and goals are huge, the entrepreneur can be called ambitious (in the best sense of the word).

Entrepreneurs make promises. To themselves, to their employees and to the community.

Solving some issue, making life easier, making more money -- these are just a few of the most popular promises made.

But the difference between a dreamer and a successful ambitious entrepreneur is that they work hard to achieve those goals

How to find the strength to actually do all of this, when the euphoria has gone and work in the office turns into a cold routine?

Write it down.

The first thing you need to do is make a written contract with yourself. It doesn't have to be a public blog post telling everyone what you plan to do. It can be a simple piece of paper that states your resolution and why you're committed to it.

Studies have shown that people who write down their goals get significantly more done. This study by Dr. Gail Matthews found that “more than 70 percent of the participants who sent weekly updates to a friend reported successful goal achievement.”

Don't be afraid to fail.

A recent study showed that people who previously took part in a “dry January” challenge generally decreased their overall use of alcohol even if they didn't manage to last the month.

So even if the goals set seem to high to achieve, you shouldn't just give up.

The higher the goals, the more you'll push yourself.

Or as author Norman Vincent Peale said: Shoot for the moon. Even if you miss, you'll land among the stars.

Trust yourself.

There are a lot of people out there who say that you're gonna fail.

From friends who jokingly say "you'll never manage to eat healthier" and "come on, you don't have to quit drinking entirely" to co-workers and bosses who think you shouldn't start your own start up.

If that happens you need to look back at the paper you wrote your plans on. Let it remind you why you're doing what you're doing and believe in yourself.

No one but you.

In the end, the only way to achieve great big dreams is to focus on it each day.

The best thing to do is to use every technique possible to hold your focus and keep your eyes on the prize.
